Is there a way to reduce spell casting time?

[Senko]

I'm just looking at some of the longer spellcasting times 6 hours for create demiplane greater for example and I'm just wondering if there's a way to reduce that time?

I am assuming for these purposes you can't just take quicken spell and reduce say a 4 hour cast down to a swift action. Since it species you can't do that with spontaneous spells (not prepared ones though so I must be missing something that would prevent wizards/arcanists from preparing quickened long casts).

Even if it is useable a lot of these longer casts are higher level than you can apply quicken too.

You can't quicken a spell with a casting time over 1 full round.

Quicken Spell. Read the second sentence.

There are a few ways to sort of speed up casting very long duration spells, but I don't think any of them would be what you are looking for.

Like you could cast Time Stop and 'shorten' the cast time by a few rounds. Since you're throwing a 9th level spell anyways why not spend an extra 25k on a Wish. Any spell you wished for would be instant.

Contingency has a lot of restrictions on what you can select, but the linked spell wouldn't have any casting time.

And the last option I can think of takes bargaining with your GM to research a new higher level version of the spell you want to cast with a shorter casting time.

You should consider creating demiplanes are like creating magic items. It will take some time. You should be thankful that the spells you are looking at are only measured in hours. Many magic items take months to make.

Spell Completion Items like Scrolls would work. Scrolls are essentially "mostly-finished" spells and just need the final words/gestures to be performed, so you could cast Create Greater Demiplane as a Standard Action.

No. Read this.

Activating a scroll is a standard action (or the spell’s casting time, whichever is longer) and it provokes attacks of opportunity exactly as casting a spell does.

So use the casting time of the spells, because they take much longer to cast.

Doh, I knew that and said the wrong thing anyway. I need caffeine.

I just realized that, ironically, crafting the scroll is going to take more time to make than casting the spell. So, even if there was a loophole for the casting time of scrolls, you'd be spending more time than what you save. The cheapest version is 2275 gp, with spell level 7, and caster level 13. It'll take 3 days to craft (at standard rate).

Assuming you can cast 9th level spells you can always use a wish to duplicate a lower level spell. The casting time for a wish is 1 standard action.

Won't help with create demiplane but a potion has a 'casting time' of 1 standard action. Useful for lesser restoration, anyway.

A magical trap activates within a round's actions. Player-made traps were nerfed heavily though, possibly in reaction to things like the Tippyverse in D&D 3.5.

So I take it that I was right and there's nothing to reduce the casting time of spells measured in hours short of using wish to duplicate it. That's unfortunate as wish is a base 25k diamond.
